Extragalactic Astrophysics, Department of Astrophysics, University of Vienna
At the Sesto Tracing Cosmic Evolution with Galaxy Clusters meeting a poster is presented this week about my work on the Gigantic (few hundreds kpc**2) Enigmatic (without a stellar counterpart) [OII]3727 BLOBS detected by MUSE in cluster XMM2215 near cosmic noon.
You can find the poster here.
On Friday July 4th I will talk at the Institute Seminar of Department of Astrophysics about a new discovery near cosmic noon: enigmatic BLOBs of ionized [OII] gas in cluster XMM2215, with no clear evidence for their photoionization source.
At the EAS 2025 a poster will be presented about my work on the BLOBs in 
cluster XMM2215 near cosmic noon. The poster will be presented in the special session SS19, Galaxies and ICM across the protocluster to cluster transition.
You can find the EAS 2025 poster here.
Our paper by C. Maier et al. with the title: Enigmatic diffuse ionized gas structures in a cluster of galaxies near cosmic noon has been published in the Astronomy & Astrophysics journal.
The BLOBs represent the Breath of Death of Dying Galaxies: They are tracing the quenching of star formation in galaxies in the center of the cluster at a redshift close to cosmic noon, z ~ 1.5. The central area of the cluster contains only passive galaxies and an AGN.

Starting in May 2025 until end of June 2025:
I will give a lecture on Extragalactic Astrophysics.
Aims, contents and method of the course
Starting in March 2025, until early May 2025:
I am giving a lecture on Galactic Structure and Stellar Systems.
As part of the Winter Semester 2024/2025 lecture on the Physical Properties of Galaxies (Master course), I will talk today about SFRs and Metallicities in Galaxies.
My proposed presentation was selected for a talk at the Beyond the Edge of the Universe conference in Sintra next week. 
My talk will take place on Thursday October 24th.
In Winter Semester 2024/2025 I will give a lecture on the Physical Properties of Galaxies (Master course) together with Prof. Ziegler.
Aims, contents and method of the lecture course on the Physical Properties of Galaxies are: Students will gain a detailed insight into the galaxy realm from a phenomenological perspective and learn various methods for measuring the physical properties of galaxies.
Contents include: Luminosity/mass distributions of stars, gas, and dust; stellar and gas kinematics; stellar and gas abundances; star formation history; chemical enrichment; galaxy scaling relations. Various analysis methods and tools for measuring these properties of galaxies using multi-wavelength observations will be discussed.
Assessment and permitted materials: There will be 1 written exam at end of semester and participants need to present a paper in the exercises. During exam no electronic or AI tools are allowed.

I gave a talk at the ESO GALCROSS conference. My abstract about the mass-metallicity relation and quenching of star formation of high redshift galaxies was selected for a 15-minutes talk at the ESO GALCROSS conference in September 2024.
